[s-cars] '95 S6 Electrical Problems Compounding

[Tony Curran]

Did you mechanic use an after-market or OE ignition switch. I used an
after-market one and had to replace it after 6 months. Was advised that the
ignition switch for sure is one item to replace with OE.

Hi All,

I have a growing list of electrical problems.  First, my ignition switch
went bad.  The spring broke so the switch did not return from the start
position.  I lived with this for a couple of months, remembering to manually
turn the switch back each time the car was started.  There is a service
bulletin on this problem that convinced me that I did not want to tackle
replacement of the switch (involves removing the steering wheel and dash).

So... I had my local mechanic replace the switch.  Just before delivering
the car to my mechanic, the autocheck display died.  My mechanic checked the
bulbs that back light the autocheck display and replaced the display with a
used one from a wrecked car.  The display is still dead.

I drove the car for a couple hundred miles with the new ignition switch.
Yesterday, when I turned the car off, the fresh air blower stayed on.  The
back light to the emergency flasher switch also stayed on.  I had to pull
the fuse for the blower to keep the battery from going dead.

I somehow suspect all these problems are related.  Obviously, the most
pressing problem is the fresh air blower staying on.  I suspect the blower
problem is related to the ignition switch replacement.  I know the heater
control module has a self diagnostic function but I doubt that will help as
the blower still runs when the heater control is off.

My instinct is that electrical problems of this magnitude would best be
dealt with by a mechanic equipped and trained for all the diagnostic
procedures described in the manual.  Unfortunately, the service manager at
the nearest Audi dealer told me he no longer has any mechanics trained to
service the '95 S6 and recommended several independent mechanics instead.
I've used several of the recommended mechanics, most of whom seem to be very
good at dealing with mechanical issues but somewhat lost when it comes to
tracing electrical problems.

Any suggestions regarding the source of the problem with the fresh air
blower or the name of a mechanic expert in electrical problems would be
greatly appreciated.

Thanks again for any help,
Bill de Alva
